Not sure about correct name for #1, but try not to rub the protective coating off the leaves.

Will try to cross pollinate them if they are open at the same time.

I dont think the sedum is a rubrotinctum because from what I read it is not supposed to survive frost and can be propogated by leaves. The one in the photo survived about -20C this winter and lots of time under the snow and I have tried to propogate it by leaves both during the summer and early spring and no luck.

One of the hardy sedums; maybe S. stefco? S. apoleipon?...

So you want to cross pollinate your unknown plant in pic #1 with Echeveria setosa?

Thank you Rina! I think it is S.stefco.

Yes, it would not hurt to try. Right?

A close up pic of the leaves might help but I think the first one is Echeveria elegans, commonly known as Mexican snowball

Here are a few more pics:

Could be this one

It could be. There are some differences in the growth of the rosette but probably it is because of different growing conditions.
